Abstract
Description
ひ化アルミニウムガリウム(AlGaAs)のような、転移スタックに非常に似た熱膨張係数を与えてもよい。したがって、温度変化が、ミラーに、特にキャリア基板を伴うスタックの接触面の近傍に、ストレス/歪みをもたらす可能性があまり高くないかもしれない。
しかしながら、いくつかの実施例では、層厚は、厚みtに対して変動してもよく、式1から逸脱してもよい。これは、広い作動域を持ちうるいわゆる‘チャープ’ミラーを製造する例において有用となりうる。加えて、“デュアル−バンド”ミラー又はダイクロイックミラーなどの多重周期構造体が可能となりうる。そして、これらの構造体は、少なくとも2つの異なる光の波長で反射しうる。“チャープ”ミラーに関し、高反射の波長域は、層の厚みを変えることによって、例えばミラーの垂直方向における層厚を徐々に増加することによって、増大する可能性がある。しかしながら、そのような変動された層厚の使用は、最大反射率を犠牲にしうる。図1は、物理的厚みに関して上記式を維持する高精度光学ミラーを示す。式1を考察することによって、高指数層及び低指数層が相互に異なる厚みを有し、それぞれの屈折率値も異なることに留意すべきである。また、キャリア基板は、重力波干渉計などの大規模な適用例において吸収効果を低減するために透明であってもよい。これらの部材は、典型的には、SiO2、サファイア、Si又はULEを含んでもよい。部材の適切な選択は、ミラーアセンブリの光共振システムへの統合を可能にしうるものであり、ミラーを離間保持するスペーサーに関して類似の又は同じ部材を使用する余地があり、以下の図3の記載も参照可能である。
